Bed Utility Rails Installation Kit

[MLB12]

Does anyone on the Forum have the original installation kit(threaded inserts, bolts, etc) for the 82215285AB dealer sold Bed Utility Rails that they haven't used? I'm thinking that if one of the Forum members does have it it's because they didn't want to use the Aluminum threaded inserts. For some reason the kit can't be purchased separately.
I'll pay a fair price and postage costs.
All help will be greatly appreciated.
